nu-air: Heat/Energy Recovery Ventilators

Nu-air: heat & energy recovery ventilators (HRV/ERV) provide the question of which is better to use: HRV or ERV? The decision of which is better to use can be both complicated and confusing. The general rule of thumb though is to use an ERV in climates where significant cooling is needed and an HRV in climates where there is not.
